Description

Apparatus and method for separating organic matter from a contaminated organic-inorganic waste stream
Technical Field
The present invention relates to improvements in methods and apparatus for the treatment and unpacking of waste material, such as municipal solid waste (msw) and food waste including source separated organic matter (sso), which is treated prior to further treatment, for example converted to biogas in an anaerobic digester and thus converted to renewable fuels, or to animal feed additives, organic fertilizers or compost.
Background
Disposal of municipal solid waste (msw) and food waste is a problem in the world.
New regulations require the complete organic transfer from landfills or bans to landfills, as well as incinerators. The organic waste stream is typically mixed with packaging materials (plastic wrap, portions of wood pallets, or long fiber wrapped materials) or with inorganics and other non-useful waste streams. The plastic and fiber packaging materials pose significant operational problems for equipment designed to separate the useful organic fraction from other waste streams. The prior art for separating useful organic fractions from msw and food waste is described in the following representative patents, namely GB 2354720 a (Ian Houghton, April 4, 2001), USA 4,852,817 (Walter Tipton, aug.1, 1989), EP 2006034B 1 (giga no tonelli, 2006), US 2016/0296986 a1 (alisandro Massone, 2016). The devices described in these representative patent documents all have serious operational drawbacks which are prevented by the novel improvements described in the following sections.
Disclosure of Invention
It is an object of the present invention to propose an improved apparatus and method for extracting organic matter from a mixed organic-inorganic waste stream or an expired pre-packaged food product prior to composting, anaerobic digester or nutrient conversion.
1. A chain is used to pre-treat the incoming waste stream and chop the plastic wrap or long fiber material, thereby plugging existing separation equipment.
2. The use of closely spaced square or rectangular openings in the screen cylinder removes a useful organic fraction from the waste stream as compared to the conventional use of circular shapes. This improvement significantly increases the efficiency and yield of the separation process.
3. A tangential discharge is used at the top of the screening drum instead of a centrally located discharge. This improvement reduces clogging of the discharge to the equipment and increases capacity.
4. Speed regulation is used on the paddle drum to adapt the separation process to different feedstocks.
Drawings
Fig. 1 provides a schematic side view of an apparatus for extracting organic matter from a mixed organic-inorganic waste stream or a stale prepackaged food product. The waste liquid (1) is poured into a feed hopper (2). The two augers (3) and (4) located at the bottom of the hopper (2) are reversed to help prevent bridging of the waste stream within the hopper (2). The feed auger (4) moves the shredded waste stream and associated gas stream through an opening (5) to the bottom of the separation apparatus.
The separating device consists of an outer shell (6) with a cylindrical or rectangular cross section, a cylindrical screening drum (7), an inner rotary paddle drum (10) with vfd driving motors (12) and a tangential discharge hole (13). Fastened to the outside of the rotating paddle drum (10) are 2 or more breaker chains (8), plus a plurality of paddles (11).
The waste liquid entering the bottom of the separation device is further crushed by a rapidly rotating chain (8) and is projected into the fixed cylinder. A plurality of blades (11) attached to the inner rotating paddle drum (10) are inclined at an angle and thus act as propellers to propel a mixture of air and spent solids in an upward spiral in the annular space between the screen cylinder (7) and the inner rotating paddle drum (10). The upward spiral or vortex, corresponding to the movement of the wringer or water nozzle, causes the spent solids to be thrown radially outward due to the centrifugal forces acting on the solids. The smaller, denser organic fraction can pass through the stationary screen drum (7) and settle down in the space between the screen drum (. and shell (6) and be discharged through opening (15) for further processing.
Larger, less aerodynamically dense residual wastes (plastic films, wooden chips, etc.) are continuously spiralled upwards to the top of the apparatus, where they are freely discharged due to the aerodynamic velocity (13), and thus out of the apparatus (14).
Fig. 2 provides a view of a square or rectangular filter area (7 a) in a still screen (7).
Fig. 3 provides a reduced top view of an apparatus for extracting organic matter from a mixed organic-inorganic waste stream or an expired pre-packaged food product. A rotating paddle drum (10) with a plurality of inclined paddles (11) blows entrained air upwards, thereby causing particles (14) of waste material to spiral upwards towards a discharge opening (13).
Detailed Description
The apparatus is an improvement of the technology involved in the biological waste recovery industry and comprises a hopper for receiving contaminated organic waste from different sources, a vertical separator for separating inorganic from organic by creating a vortex effect in a stationary screen cylinder, wherein solid contaminants (paper, plastic, metal) are blown in a spiral manner similar to that removed from the top upwards and from the top, while the organic fraction passes through a filter cartridge and is removed from the bottom. The apparatus may be supplemented by a sand removal system that removes all sand and grit prior to the digester.
A major operational problem with the prior art devices is that the waste stream entering the filter cartridge (7) may contain large pieces of plastic packaging film and or long fiber strapping material that eventually wraps itself around the shaft of the paddle (11) and paddle screw and blocks the device. Such plugging requires shutting down the separation process and manually removing the plugging is a labor and time intensive process. The inventors have found that this type of fouling and clogging of the blades can be prevented by attaching 2 or more chains (8) to the outer surface of the paddle drum (10) and adjacent to the inlet (5). The length of the chain (8) should be longer than the length of the blades (11). Preferably, the links constituting the chain (8) should have sharp edges, similar to the chains used on cars and trucks for travelling on icy surfaces. The sharp edges help to shred large pieces of plastic packaging film and long fibre strapping, but are not essential to the invention, as the main function of the chain (8) is to throw this large waste outwards so that it does not get tangled on the blades (11). Thus, the upward movement of the lightweight material starts at an outer location of the vortex rather than the central axis. The present invention (adding chain (8) to the bottom of the paddle drum (10)) thus solves the main operational problems of the prior art separation techniques, where there may be an accumulation of long fiber material settling at the bottom of the filter screen.
Another problem with existing devices is the efficiency of the separation of the organic fraction. The perforated drum of the existing apparatus uses circular perforations, which impose limitations on the efficiency of the process. The present invention uses square or rectangular perforations which, in the case of square openings, provide a much larger open area than existing circular openings. This increased area allows for greater throughput or, if desired, better fractionation of organic waste streams from other wastes. Replacing the perforations with square or rectangular openings will increase the drainage of the liquid while having a longitudinal part of the rectangular opening in the vertical position and a suitable width reduces the contamination of the separated organic fraction.
A third novel improvement that improves the operation of the organic waste separation device is the location of the discharge (13). Existing systems use discharge and are located at or near the radial center of the screen drum (7). This position, however, often results in a blockage at the auger (13) inlet, as the waste material (14) is blown through the auger (13) inlet rather than into the discharge (13) inlet. The novel improvement shown in figure 3 is to position the discharge means (13) so that it is tangential to the screen cylinder (7). The waste (14) is now blown directly into the outlet (13) and is not forced to be hard 90 degrees into an auger. This reduces the down time required for cleaning, thus increasing the efficiency of operation and the amount of contamination that can be vented. It also eliminates the friction of the vortex created by the accumulated solids prior to discharge, resulting in reduced energy requirements.
A fourth new improvement is the use of different speeds of the paddle screw driven by the motor (12), said motor (12) having an adjustable speed (sso) under the action of the different products treated, dry food, packaged vegetables, pots, fruits and the like.
